The `Schedule referred to in these Letters Patent and making part of the same.

T all whom fit 'may concern .v y

Be it known that I, WILLAM GLUE, ofMnskegon, in the county of Muskegon and State of Michigan, have invented a new and useful Improved Door-Latch and Catch; and I do hereby declare the following to,

be a'full, clear, and exact description of the same, reference being had to the accompanying drawing, in which Figure l is a perspective view of the inner or rear side`of my latch.

Figure 2 is an elevation showing the form of the keeper for the same.

This invention relates to that class of latches which is released bya straight pull Without turning a knob; and

It consists'in constructing the spring-latch in one piece, arranged within a suitablecase having a'locking eccentric, in such a vmanner as to operate in vertical lines to engage with the keeper upon the. doorjamb, as will be hereinaftermore fully described.

That the constrlictiou and operation of this invention may be thoroughly understood, I will particularly describe it.

A is the case or frame within which the latch or holt is located. Said frame may he constructed of any suitable materialV and in any appropriatefform.

B is the latch, which is lodged withinfthe case A, and Vis provided with a spring as apart of itself; as in iig. 1, to insure itsl continued engagement with the keeper C during the timer the door remains closed.

The keeper G is made to project from the doorcase, as shown in g. 2.

It will now be observed that'theusurfaces of both keeper and latch are made inclined at those portions where said surfaces come in contact, and said inclination is such that the keeper ujhen a direct pull is applied to the door'. But

bolt or latch will rise out of its it is required to'lock orsfasten the catch sometimes, so that the door cannot be thus liberated, and to this end I arrange an eccentric dog, D, which, when brought into position, (shown in tig. 1,) will prevent any movement-of' the latch, and eiectually lock the door.

The dog D mty be operated in any convenient manner, and when .thrown back it offers no impediment to the movement of the latch.

In many situations a straight-pull latch is more convenient and desirable than almob or lifting-latch, as upon partition-gates, out-house doors, closets, &c., aside from the score of cheapness, and in such situations ny inventionis applicable.

I do not claim a spring-pull latch broadly, as ain aware that the same is not new.

Such latches,- however, have been made to operate in horizontal lines to engage with a keeper upon-a door-jamb, and are there 'ore' objectionable from the fact that, if -the door sags upon its hinges, theend of lth'e latch is carried' below the keeper, and cannot engage therewith.

By my "invention the latch operates in vertical lines with relation to the keeper, and consequently is not materially adected by the sagging of the door.

Having' now described my invention,

What I claim as new is- The straight-pull spring-latch B, made in one piece,

Aand ihefeccentric I), constructed as described, and arranged withinA the frame A so "thatthe latch shall operatevertically with relation to the keeper C, as

hereiufset forth and shown.

WILLIAM GLUE.
